For those populations with high levels of genetic variation of different regions such as J.K and J.N of Libya It can be suggested that their habitats be protected and the exploitation of wild resources be forbidden. For ex situ conservation, the Research centers want to carefully design and establish a germplasm bank for this species. According to the field survey, the over- exploitation of natural populations and the extensive loss of habitats have seriously threatened the populations, which should be the priority sites for ex situ conservation. Moreover, further information on cultivation, which may affect the maintenance of variation in the population, is needed before it can be accepted that this is a satisfactory conservation strategy currently, the bulk demands of such populations for its great medicinal value cause the over-exploitation of wild resources.The results showed high levels of genetic diversity between five populations where the amount of variation within populations were low. The present study is the first assess to examine the genetic diversity of there species in Libya. Both marker systems used in this study had high levels of diversity in these assessments. (Hadian et al 2008). Variation among populations of summer savory (Satureja hortensis) of horticultural traits, chemical and RAPD molecular markers examined. Thier results showed that both environmental and genetic factors contribute to the observed changes, and it showed high polymorphism. In general, five populations are characterized by a high genetic variability that is typical for a species with wide distribution ranges due to local short-scale evolutionary processes (Hamrick and Godt, 1989).Lamiaceae (Labiatae)
